Does anyone here own a six cylinder that makes more that 110 horsepower and doesn't have to use a blower, efi, or nitrous. I want to do something different but not spend a fortune. I would like to pull 200 horsepower out of an I6. With the weight of the car, that will make for a suprisingly quick ride. But I do not want to bust the bank here. The idea is a low budget power build up. I want to hear stories. i've heard plenty of people tell me "Go check out FordSix.com but i want to hear whay yall have to say about tips on better horsepower from an I6.
Six's, no NOS, Blowers, or EFI..

Well, it's not a Ford, but I went to see a 69 Barracuda with a 225 slant six project car for Car Craft Magazine a few years ago. It had a 4 barrel carb, split full lenth headers, high perf cam, 4 speed stick, etc. It pulled hard for a six, of course the long stoke of the slant six helps.

The forum specializes in 6 cylinders. fordsix.com Also check out http://www.cliffordperformance.com . A little expensive but they have some stuff. There is a store with a lot trick stuff built for the six. The main problem in the straight six is the head. It just does not flow. Get some aussie head. They flow a lot better or there was talk of a head from Argentina which might still be an option.

Ok, I'm guessing you don't want EFI in order to keep it cheap. But you should be able to get a cheap 300 I6 with EFI from an early 90s pickup for very little. At one time I test drove a 351, 302 and a 300 in early 90s pickups, and to me the difference was very slight if any.65straightsick said:
Or just buy a 300 6 that doesn't have efi. A 300 should make more than 110 horsepower no problem. I actually would be surprised if my 250 in my '70 doesn't make 110. It keeps up with traffic anyway. There's no substitute for cubic inches. The 200 isn't designed to make much power, but the 300 is a lot beefier.

The aussie head is pretty much a bolt on. http://www.fordsixparts.com/OZ%20250-2V.htm check it out. I was trying to put some innuendo. But anyways its not cheap but neither is going fast.

You can usually find cheaper ways to do things. I think it would be cool to see/drive a hotrodded 6, but a small 8 is the easier/less expensive way to get there. Or buy a newer, bigger I6 (get something 15 or more years old out of a junker).65straightsick said:
You could also probably get a complete running motor out of a junkyard for less than that head, even if you had to rebuild it, if you did the work yourself. Probably pushing it some, but $600 for an I6 head is just insane to me. I personally have more time than money, so junkyards are my friends.
According to Ford, the 300 made only 10 hp less than the 302, but quite a bit more torque than the 302. Wouldn't a 300 be hard to fit under the hood?Hack said:
For the 200, I'd say the cheapest way to help (not solve) the head breathing problem is to buy one from a late 70s early 80s model. They have the largest intake valves available stock (the CR was lowered a lot on those years, but its easily fixed by milling). At one time, Clifford was developing an aluminum head but I dont know much more about it than that.
I have added performance stuff to mine (headers, bigger carb, etc.) but I can't give you any numbers. Just that she woke up

Good point, I have no idea if it would fit under the hood. I would just assume so. But you'd probably want to measure the height of it from the motor mounts before trying. It's possible that the upper intake is taller on a pickup than on a car, since there's room.TheWolf said:According to Ford, the 300 made only 10 hp less than the 302, but quite a bit more torque than the 302.

racer walsh also has alot of inline 6 performance parts. i6 fords are become very popular to mate to volkswagen transaxle and are beeing used in lots of sand rails, so the market for the performance parts it expanding rapidly
